IMPROVEMENT IN MACHINES Specification forming part of Letters Patent No.

FOR TRIMMING SHOE-SOLES.

151,806, dated June 9, 1874; application tiled September 2S, 1872.

To all whom it may concern:

Be it known that I, BENJAMIN J. TAYMAN, of the city of Philadelphia, in the State of Pennsylvania, have invented certain ImproveandWelts, and edge-settingthe same, of which the follow-ing is a specification:

My invention relates to a jack -earriage which has alternately a sliding` and semi-rotating movement, produced by suitable mechanism, in such a manner that, in the semi-rotating movement, the heel and toe of a boot or shoe are brought into position to' be operated upon by the trimming or burnishing tool, and, in the alternate sliding movements, the shank and fore parts are also brought to the tool, so that the whole circumference of the sole is presented to the tool while the carriage moves in an unvarying vertical plane. The invention further relates to the combination, with said carriage, of a jointed tool-holder, by means of which the operator is enabled so to guide the tool that it shall be caused to operate upon the edge of the sole throughout all the varyin g curvatures and bevcls of said ed ge. The invention further relates to giving a reversible rotatory movement to the burnisher by means of crank-arms of unequal length on two shafts, one of which is intermediate between the burnisher, to which it is geared, and the other shaft, which has a continuous revolution.

Figure l is a plan view of the improved machine. Fig. 2, Sheet No. 2, is a front elevation of the same, the cutter-head P being left o`. Fig. 3, Sheet No. 3, is an end view of the same. i Fig. 4, Sheet N o. 4, is an end elevation,partly in section, of the head B, provided with the jack C, by which the shoe is held for the trimming and burnishing operations. Figs. 5 and 6 are views at right angles lto each other of the l shaft D and disks J and J2. Figs. 7 and 8 are like views `of the disk J1. Fig. 9 is an isometrical view of the sliding plate M. Fig.

11 and 12 are views at right angles to each other of the cutter-head1?, and parts attached. Fig. 13 is a perspective view of the Acutterhead, with its connections detached therefrom.

Like letters in all the figures indicate the same parts.

The several parts of the machine are supported by the table A, having ends b b. At one end of the table is a stationary head, B, which is provided with a jack, G, connected with the inner end of the revolving shaft D, which has a slow movement imparted to it by means of the spur-wheel E on its outer end gearing into the pinion E on the shaft F, the said shaft being connected with the drivingshaft G by means of the belt H and pulleys I I.' The several parts of the jack are shown in detail in figures from 4 to 10, inclusive. J is a disk, permanently connected with the revolving shaft D near the inner end, and J1 a disk which has a loose lit on the same, to admit of the shaft turning freely in it at times when it remains in a state 'of rest, for the purpose hereinafter described, the said disk being provided with two pins, c and c, which fall alternately into the notch. j' of the spring-catch K during the revolutions of the shaft D, whereby the disk is held in a state of rest until the cani L, which is attached to the inner end of the pin g of the disk J, and which moves freely in the space h between the disks J and J1, approaches the spring, and bears against the notched end and disconnects it from the pin c then in connection with it, the said cam being prevented turning by means of the inner edge of the arm Q'. on the outer end of the pin resting against the concentric part of the plate j of the heafl B, and the cam, by thus bearing against the pin, causes the disk Jl to revolve, in connection with the disk J, one-half around, and until the said arma' in the forward motion of the disk falls into the depression k of the plate j, as seen in Fig. 4, allowing the pin g to turn freely and disen gage the cam from the pinc. Then the other pin c comes into connection with the notch j" of the spring-catch K, whereby the disk J1 is again held in a state of rest until the cam L comes around and releases the spring-catch from the pin. During the resting positions of the disk J l the crank-pin l of the shaft D, which 4projects from the disk J2 in the recess m of the disk J1, and which has a free movement in the cross-slot n of the sliding plate M, connected with the ways o 0 of the disk, having passed its dead-centers, carries the said plate forward,

and thus gives a sliding movement to the fr @Erica plate. N is a carrier for the shoes, and is made fast to the plate by means of the screws p, so as to have a revolving movement imparted to it to present the toe and heel of the shoe to the center, and a reciprocating movement to present the intermediate parts to the same. The throw of the carrier is regulated to suit dili'erent lengths of shoes by making the crank-pin Z adjustable by means of the slot q in the disk J2, the pin being fastened in its adjusted position by means of the nut g. The carrier N is provided with a toe-rest, r2, and a heel-pin, r3, which are movable in the longitudinal slot s, and adjusted by means of a right-and-left screw, O. The ends of the screw are connected with the projections t t of the carrier, the longitudinal groove u of the plate M guiding the sliding heads e o on the inner ends of the pieces r2 and r2, the toe and heel rests being thus thrown in or out from the center of the carrier by the operation of the screw in adaptation to the different lengths of shoes. K1 is a spring, which is provided with a shoe, K2, that binds on the periphery of the disk J1, to steady it as it is borne forward, and as it comes to a state of rest. P is a cutter-head. (Shown in Figs. l, 1l, 12, and 13.) The head has a cross-handle, Q, on the center stem fw, for manipulating it, in combination with the handle Q', that projects from the jointed arm R, hung on the outer end of the stem, and confined by means of a screw, S, which also confines the guard T and weltcutter U. V is the knife for trimming the edges of the soles, held in place by means of the screw YV, which passes through its slotted end, and allows it to be set up against the guard as its angle edge wears away, th'e end being ground olf, as occasion requires, to admit of the setting up. There is a socket, X, which is jointed at one end to the outer end of the arm R, and also connects with the front end of the rod Y, (seen in Figs. l, 2, and 3,) so as to be capable of sliding backward or forward thereon in the adjustment of the cutter-head to the work. The said rod Y is jointed to the rod Y', and the latter, at its rear end, to the slotted rest Z, the rod Y turning on the pin m a', to admit of the free forward movement of the cutter-head. 'The vertical slot fr, through which the screw y passes, and contines the bar to the table A, admits of the bar being set backward or forward in accommodating the cutter to the right position of the shoe. With the rear end of the frame c c is connected one end of the rod i i, the other end of which is provided with a yoke, j j, with which is connected the yoke j jl on the upper end of the rod t' il, the yokes being connected by means of the rod z' i2. The rod i il is provided, at its lower end, with the yoke jj2, that connects with the driving-shaft Gr. The rod is supported by means of the curved extension of the bar Z and the screwbolt 7c 7s, which passes through the slot l l of the bar, for fastening the rod in its adjusted position, either backward or forward. The

said yoke j y2 is provided with a revolving shaft, m m, on whichis a pinion, 'n n, that gears into the whceln n on the driving-shaft G. On one end of the shaft m m is a disk, o o, and on one end of the rod 'i i2 there is a similar disk, o o. A crank-pin, p p, projects from the disk o o, and a like pin, p p', from the disk o o', but at a greater distance from the center of motion than that of the other disk. The rod q q is connected with the two pins. Then, by the. revolutions of the driving-shaft G, the disk o ois caused to make successive revolutions, while the disk o 0, in consequence of the crank-pin being farther from the center of motion, makes only a partial revolution, and, consequently, has an alternately reverse movement. There is a belt, r 1, which passes over the pulley s s on the rod t' t2, and the pulley s s1 on the shaft m m; and a belt, r r', is passed over the pulley s s2 and the pulley s s2 on the burnisher-shaft b b. The former belt is dispensed with except when continuous rotary cutters are used instead of the ones above described. By the use of the latter belt, a reversible rotary motion is transferred from the rod '13 i2 to the burnisher a a, whereby the latter is caused to perform its work in a similar manner to that of a handburnisher. l

During the burnish in g operation, the cutterhead may be removed from the machine, as in Figs. 2 and 3, and when the cutters are being used the connecting-shaft q q may also be removed.

I claim as my inventionl. In machinery for trimming and burnishing the edges of boot and shoe soles, a jointed tool-carrier having the capacity to follow all the varying cnrvatures and bevels of the soleedge, in combination with a jack and carriage having alternate semi-rotary and sliding movements, substantially as set forth.

2. The combination of a jack-carriage with the rotary toothed disk or wheel E, for imparting, through intermediate locking and unlocking devices, semirotary and sliding movements to said carriage and its jack, the.

said disk or wheel being arranged on the shaft D, which is the axis of rotation of said carriage, substantially as shown and described.

3. The combination of the sliding plate M, carrier N, shaft D, gear-wheel E, disks J and J1, springs K and K1, and brake-shoe K2, together forming mechanism for giving the jack U its required semi-rotary and slidingmovement, substantially as set forth.

4. The combination of the shaft m fm, rod t' i2, disks 0 o and o o', crank-pins p 19 and p p, and connecting-rods q q, and intermediate pulleys s s2 and s s2, all for the purpose of giving a reversible rotary motion to the burnisher c u., substantially as set forth.
